Dab tsi yog cov yam ntxwv ntawm dawb corundum, xim av corundum thiab liab corundum?
Dawb corundum yog dab tsi?
Dawb corundum yog tsim los ntawm kev lag luam txhuas oxide hmoov ua raw khoom, uas yog txias tom qab melting ntawm qhov kub ntawm ntau tshaj 2000 degrees nyob rau hauv lub arc. Nws yog crushed thiab zoo li tus, tshem tawm los ntawm kev sib nqus sib nqus, thiab muab faib ua ntau qhov ntau thiab tsawg. Nws qhov kev ntxhib los mos yog ntom, nws hardness yog siab, thiab cov khoom tsim cov kaum ntse ntse.
Cov yam ntxwv ntawm dawb corundum
Dawb corundum yog crystallized los ntawm electromelting. Nws muaj purity siab, zoo tus kheej ntse, acid thiab alkali corrosion kuj, kub tsis kam thiab ruaj khov kub lub xeev kev ua tau zoo. Dawb corundum hardness yog me ntsis siab dua xim av corundum, toughness yog me ntsis qis, siab purity, zoo tus kheej ntse, muaj zog sib tsoo muaj peev xwm, me me tshav kub, high efficiency, acid thiab alkali corrosion kuj, kub thermal stability.
Scope ntawm daim ntawv thov ntawm dawb corundum
Dawb corundum yog tsim rau kev tsim cov ceramic, resin-consolidated abrades, sib tsoo, polishing, sandblasting, precision casting (precision casting corundum), thiab lwm yam, thiab tseem tuaj yeem siv los tsim cov ntaub ntawv qib siab refractory. Haum rau ntau yam khoom siv high-end, thev naus laus zis lossis kho vajtse thiab lwm yam khoom siv kho kom zoo nkauj, sandblasting nto dawb tsis muaj impurities, tsis muaj teeb meem tu. Fine dawb corundum tuaj yeem siv ua polishing taub hau.
Brown alumina yog dab tsi?
Brown corundum, tseem hu ua carborundum, yog xim av dag corundum ua los ntawm bauxite, carbon cov ntaub ntawv thiab hlau chips los ntawm melting thiab txo nyob rau hauv ib tug hluav taws xob rauv, yog li nws muaj npe rau qhov no. Cov tshuaj tseem ceeb ntawm cov xim av corundum yog Al2O3, nws cov ntsiab lus yog 94.5%-97%, thiab muaj me me ntawm Fe, Si, Ti thiab lwm yam.
Cov yam ntxwv ntawm xim av corundum
Nyob rau hauv daim ntawv thov txheej txheem, nws muaj cov yam ntxwv ntawm non-initiation, non-pulverization thiab non-cracking, tshwj xeeb tshaj yog nws cov nqi kev ua tau zoo yog ntau dua li cov tsoos xim av corundum, thiab nws dhau los ua aggregate thiab muab tub lim ntawm xim av corundum refractory.
Daim ntawv thov Scope ntawm xim av corundum
Xim av corundum particle loj xuab zeb yog manually xaiv xim av corundum thaiv, siv dov, pob milling, Barmack thiab lwm yam khoom ua, particle loj F8-F325, tsuas yog siv rau polishing, sib tsoo, industrial sib tsoo, thiab lwm yam. ntxuav raws li tus neeg yuav tsum tau ua, pickling thiab lwm txoj kev ua, kom tau raws li qhov sib txawv ntawm cov neeg siv khoom.
Liab corundum yog dab tsi?
Cov muaj pes tsawg leeg ntawm liab corundum yog tsuas yog -alumina, tseem hu ua chrome corundum, ruby. Tam sim no kev ua lag luam feem ntau yog xim liab corundum.
Cov yam ntxwv ntawm liab corundum:
Liab corundum ntxiv 22% chromium rau lub hauv paus ntawm dawb corundum, ua los ntawm hluav taws xob arc rauv melting, xim yog ntshav. Lub hardness yog me ntsis siab dua li cov xim av corundum, zoo ib yam li dawb corundum, thiab cov microhardness yuav yog 2200-2300Kg/mm2. Toughness yog siab dua dawb corundum, me ntsis qis dua xim av corundum.
Scope ntawm daim ntawv thov ntawm liab corundum
Cov cuab yeej abrasive tsim los ntawm nws yog tsim rau kev sib tsoo high-carbon steel, high-speed steel thiab nyias-walled qhov chaw, thiab abrasive kuj siv tau raws li kev sib tsoo, polishing cov ntaub ntawv, precision casting xuab zeb, tshuaj tsuag cov ntaub ntawv, tshuaj catalyst cab kuj, tshwj xeeb ceramics. , high-qib refractory khoom, thiab lwm yam.
Feem ntau los ntawm qhov pom ntawm hardness thiab toughness:
Hardness: Dawb corundum> Liab corundum; Brown corundum;
Toughness: Brown corundum> Liab corundum; Dawb corundum.
Ntxiv rau qhov siab hardness, dawb corundum yuav tsis raug coj mus rau hauv cov xim thaum sib tsoo, uas yog tshwj xeeb tshaj yog haum rau kev sib tsoo ib co xav tau cov khoom hlau.
Brown corundum yog feem ntau corundum series abrasive xuab zeb. Liab corundum yog qhov chaw nyob nruab nrab.
